The woman also told investigators that she was actually having sex with her own father, who had claimed he was chased out of the park by the group of teens when they attacked his daughter, officials said.

She also told authorities there was no gun involved in the January 7 incident, Brooklyn District Attorney Ken Thompson said.

“The complainant, as well as her father, provided multiple inconsistent accounts to NYPD Detectives and to experienced Special Victims prosecutors about important material facts in this case,” Thompson said in a statement.

“The complainant has recanted her allegations of forcible sexual assault and the existence of a gun, and she does not wish to pursue criminal charges against any of the defendants. She also refuses to cooperate with any prosecution against her father, who was engaging in sexual conduct with her.”

Early reports of the incident described a nightmarish scene, where a group of teens set upon a young woman and her father who were sitting near Osborn Playground’s handball courts about 9:10 p.m.

“Get the f*** out of here,” one teen was accused of yelling at the father, who claimed he ran to a bodega for help but was turned away.

“That night, this young woman’s father and the five young men engaged in conduct that was reprehensible and wrong, but because of the lack of reliable evidence, criminal charges simply cannot be sustained,” Thompson said.

Charges will not be brought against the woman, officials said.

“It is my fervent hope that this young woman gets all the support that she needs going forward,” Thompson said. “My office, including our victim advocates who have been working with this young woman, stand ready to provide her with any assistance she may need.”
